Special Issue Information

Dear Colleagues,

The living and non-living resources present within the marine environment constitute the fundamental “marine natural capital” that exists within the global oceans, serving as the foundation for a range of marine ecosystem services. In recent decades, human activities have exerted heightened pressures on marine ecosystems, often resulting in their deterioration and the loss of biodiversity. Soil management practices rooted in conservation offer a spectrum of benefits, including the production of food, fuel, and fibres, as well as the control of erosion, the facilitation of water infiltration, the mitigation of nutrient runoffs, the regulation of greenhouse gases, and the curbing of agricultural pests. The rich and varied array of organisms residing below the soil surface significantly impacts all the ecosystem services that soil provides, the same as marine ecosystems. This Special Issue is dedicated to research focused on the restoration of environmental matrices via the design of innovative bio-based approaches, with specific attention paid to the study of the biodiversity and complexity of microbiota that are able to transform environmental contaminants and preserve the biodiversity of the treated matrix. The objective of the bio-based technologies designed for environmental restoration is not only to provide a decontaminated matrix, but to also provide a decontaminated matrix that is capable of returning ecosystem services.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Water is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

To accelerate the depletion of total petroleum hydrocarbons, a hydrocarburoclastic ascomycetes, Lambertella sp. MUT 5852, was bioaugmented to dredged sediments co-composting with a lignocellulosic matrix. After only 28 days of incubation, a complete depletion of the contamination was observed. The 16S rDNA metabarcoding of the bacterial community and a predictive functional metagenomic analysis were adopted to evaluate potential bacterial degrading and detoxifying functions. A combination of toxicological assays on two eukaryotic models, the root tips of Vicia faba and the human intestinal epithelial Caco-2 cells, was adopted to assess the robustness of the process not only for the decontamination but also for the detoxification of the dredged sediments. Bacterial taxa, such as Kocuria and Sphingobacterium sps., resulted to be involved in both the decontamination and detoxification of the co-composting dredged sediments by potential activation of diverse oxidative processes. At the same time, the Kocuria sp. showed plant growth-promoting activity by the potential expression of the 1-aminocyclopropane-1-carboxylate deaminase activity, providing functional traits of interest for a technosol in terms of sustaining primary producer growth and development.
